Full-automatic mechanical vehicle height regulation oil-gas suspension frame

Abstract

The invention relates to a full-automatic mechanical vehicle height regulation oil-gas suspension frame, which belongs to the technical field of oil-gas suspension frames, wherein an oil-gas spring upper support seat, an oil-gas spring upper cylinder tube and an oil-gas spring lower cylinder tube are fixedly connected to form a cylinder body; a low-voltage energy accumulator, a high-voltage energy accumulator and an orifice valve are all in external arrangement, and are communicated with corresponding interfaces arranged on the oil-gas spring upper support seat; a piston rod slides upwards and downwards along the inner wall of the oil-gas spring lower cylinder tube; a regulating rod is a hollow rod and can slide upwards and downwards along the inner wall of a regulating sleeve pipe, the upper end is connected with a regulating rod interface arranged on the oil-gas spring upper support seat, the lower end is provided with a lead-in valve and a regulating rod oil hole, and the side wall of the lower part is provided with an oil drainage hole and an induction passage; and the regulating sleeve pipe is a hollow rod, is fixed on the inner wall of the piston rod, and is coaxial with the regulating rod and the piston rod, the upper end and the lower end are provided with sealing rings, and the lower end of the regulating sleeve pipe is provided with a lead-out valve and a regulating sleeve pipe oil hole. The invention can realize the automatic regulation of the vehicle height without an electronic control system, and has the advantages of simple structure, high reliability and good heat radiation performance.

Description

Technical field: [0001] The invention relates to a fully automatic mechanical height-adjusting oil-pneumatic suspension, which belongs to the technical field of oil-pneumatic suspension. Background technique: [0002] Motor vehicles such as passenger cars and trucks have a large and frequent load change range. For vehicles equipped with ordinary suspensions, the height of the vehicle body cannot be adjusted according to the load change. The change of vehicle body height causes the change of suspension kinematics characteristics, aggravates tire wear and increases rolling resistance. Increased fuel consumption; the change of body height will also reduce the dynamic stroke of the wheel jumping up or down, increasing the breakdown probability of the suspension and destroying the comfort; if the load of the vehicle increases, the body will drop, which also reduces the Passability of vehicles. Therefore, the vehicle height adjustment system can improve many performances of the ...
